I had very bad flu and stayed days without feeding myself ...

These days I had a very bad flu, I stayed two days without feeding myself. After that I feel that my stomach will not accept the food; even when food implies that I am still hungry. Is this serious?
Expert answer:

It is not something serious and should pass in the next few days, it may even be an inflammation in the stomach caused by the flu, lack of food and the use of flu remedies.
